Fixed

• NestJS archetype naming drifted from the clustering that produced the cluster:
  a *.repository.ts (or *.dto.ts / *.entity.ts / *.interceptor.ts / ...)
  cohort was correctly role-bucketed by signatures._NESTJS_ROLE_SUFFIXES (fifteen
  roles) but the _TS_PRIORS naming table hardcoded only six suffixes, so a
  feature-co-located *.repository.ts cohort (one per feature dir, no dominant
  directory) fell through to a meaningless cluster-<hash> name. .dto.ts /
  .entity.ts survived only by luck of directory layout (a shared dto/ /
  entities/ dir). The naming table's suffix priors are now generated from the
  SAME _NESTJS_ROLE_SUFFIXES map, so the two can never diverge again, with a
  guard test asserting parity. Surfaced by the step-7 fresh-repo re-verification
  on an idiomatic per-feature NestJS layout.
• Python line-length enforcement no longer false-positives on a mixed per-app
  E501 layout. When a repo's root ruff config opts out of E501 (the common
  line-length = N + ignore = ["E501"] "format toward N, don't fail on length"
  pattern), _read_python_format correctly drops line_length -- but that left
  the derived fmt empty, indistinguishable from "root declared no config", so
  the scan_subdirs fallback (meant only for a config-less root) resurrected an
  enforcing sibling app's line_length repo-wide and flagged every long line in
  the E501-ignoring apps. The fallback is now gated on the root having declared no
  ruff/black config at all, not on the derived fmt being empty, so an explicit
  root opt-out is authoritative. Surfaced by the step-7 fresh-repo re-verification
  on a mixed-config Django repo.
